SEALED SYSTEM TROUBLESHOOTING / DIAGNOSTICS TABLES
NORMAL OPERATING PRESSURES TABLE NOTES:
• Only enter the sealed system to check pressures if the Error Code Troubleshooting Guide and General
Troubleshooting Guide could not pinpoint the cause of the temperature problem.
• Always use solder-on process valves when entering the sealed system. Do NOT use bolt-on process valves as
they are prone to leak.
• Whenever servicing the sealed system, the high-side filter-drier MUST be replaced.
• Pressures listed below are not indicative of initial pull down, but rather of a steadily running and properly function-
ing appliance.
• Pressures listed are for reference only, as actual pressure readings may vary because of one or more of the fol-
lowing reasons:
1. Ambient temperatures (Pressures are based on a 21°C (70°F) Ambient).
2. Temperature set-points (Pressures listed below are based on set-points of -18°C (0°F) in freezers and 3°C
(38°F) in refrigerators)
3. Food load quantity and temperature.
4. Condenser cleanliness.
5. Whether or not one or both refrigeration systems are operating.
6. Gauge calibration.
